@valentin-pinkau I created the route POST api/v8/aiModels/register. It expects a json object body with

id: String, // must be unique and a valid MongoDB ObjectId, compare https://pymongo.readthedocs.io/en/stable/api/bson/objectid.html
dataStoreName: String, // "localhost" for standard dev setup, "webknossos.org" for webknossos.org (data-humerus)
name: String, // Must be unique.
comment: Option[String],
category: Option[String] // if present, must be one of em_neurons, em_nuclei, em_synapses, em_neuron_types, em_cell_organelles

It expects that the model is already present in the .aiModels directory, compare worker. The route does not currently assert that the model is there on disk and usable.

The X-Auth-Token HTTP header must be set to the user’s auth token.

Do you think that will work for the PublishModelTask?
